📡 Ping & Port Checker

Ping host and check port availability

TL;DR:

Ping sends ICMP requests to a host and measures response time (RTT), packet loss, min/avg/max latency. It uses ICMP, unlike TCP port checks. A site not responding to ping does not mean it's down — hosts often block ICMP. Complement with HTTP and DNS checks.

How Do Ping and Port Scanning Work?

Ping sends ICMP packets to a host and measures response time. Port scanning checks which TCP ports are open and accepting connections — helping diagnose serviceavailability issues.

Configurable Ping

Choose packet count (3, 4, 6, 10). Stats: min/avg/max latency and packet loss.

Common Port Scanner

Check 14 key ports: HTTP, HTTPS, SSH, FTP, SMTP, MySQL, PostgreSQL, and more.

Cloud-Based Check

Testing from our server — see site availability from outside, not just your local network.

Uptime Monitoring

Need constant monitoring? Create a monitor — checks every minute with notifications.

Common Mistakes

❌

ICMP blocked = server is downMany servers block ICMP. Ping fails but site works — check ports instead.

❌

High ping = server problemLatency depends on geography. 150ms between continents is normal, not an error.

❌

Closed ports — cause for alarmClosed ports of unused services are good. Unnecessary open ports are a risk.

❌

One check = sufficientNetworks are unstable. A single timeout ≠ a problem. Check multiple times or set up monitoring.

Best Practices

✓

Combine ping and port checksPing shows host availability, ports show specific service availability. Use both.

✓

Check from different locationsThe problem may be local. A cloud test shows the real picture.

✓

Close unused portsEvery open port is a potential attack vector. Keep only necessary ports open.

✓

Set up monitoringManual checks do not scale. Set up automated monitoring with notifications.

Ping and Port Check Tool

Test server availability with ICMP ping and check if specific TCP ports are open. Our tool measures response time (latency), packet loss, and connection status from a server in Russia. Check common ports: HTTP (80), HTTPS (443), SSH (22), FTP (21), SMTP (25/587), MySQL (3306), PostgreSQL (5432), and any custom port.

The ping tool measures round-trip time (RTT) to any server, helping diagnose network latency, packet loss, and connectivity issues. It supports both ICMP and TCP ping modes, and shows min/avg/max response times with jitter calculations.

Useful for checking server availability before deployment, diagnosing slow connections, and comparing response times across regions. For network path analysis, try traceroute. For comprehensive server monitoring, combine with uptime monitoring and page speed analysis.

Frequently Asked Questions

What is ping?

Ping is a network utility that sends ICMP packets to check host availability. It measures round-trip time (RTT) in milliseconds and packet loss, helping diagnose network issues.

What is a good ping time?

Under 20ms is excellent (local network). 20-50ms is good (within country). 50-100ms is acceptable (intercontinental). Over 100ms may be noticeable. For gaming, under 50ms is critical.

How to check if a port is open?

Our tool lets you check any TCP port. Enter an IP or domain and port number. An open port means the service is listening and accepting connections. A closed or filtered port may indicate a firewall.

Why is my ping high?

Common causes: geographic distance to server, network congestion, ISP issues, Wi-Fi interference, VPN/proxy in the chain. Use traceroute for diagnosis — it shows where the delay occurs.

What common ports should be checked?

Key ports: 80 (HTTP), 443 (HTTPS), 22 (SSH), 21 (FTP), 25/465/587 (SMTP), 110/995 (POP3), 143/993 (IMAP), 3306 (MySQL), 5432 (PostgreSQL), 6379 (Redis), 3389 (RDP).

What is packet loss?

Packet loss is when some of the sent data does not reach its destination. 0% is ideal, 1-2% is acceptable, over 5% is a serious issue affecting speed and connection stability. Causes: congestion, faulty equipment, interference.

What is the difference between TCP and ICMP ping?

ICMP ping uses the ICMP protocol and checks basic host availability. TCP ping establishes a connection to a specific port and verifies if the service is running. TCP ping is more useful when ICMP is blocked by a firewall.
